Also, other structural practices were added to later buildings, such as placing horizontal bond beams to transfer structural loads to the adobe roof. The extension of vigas some feet outside of the wall is a standard practice. This was used for the creation of portales or covered porches.
The design is created by crossing the strips to form a grid or weave. [1] Latticework may be functional – for example, to allow airflow to or through an area; structural, as a truss in a lattice girder ; [ 2 ] used to add privacy, as through a lattice screen; purely decorative ; or some combination of these.
The intervals for the blocks are specified in the building code or as calculated by a structural engineer. Blocking also resists the rotational movement, or twisting, of floor joists as they deflect under load. This may take the form of diagonal cross bracing, or herringbone, bracing between floor joists.
This is an example of a "double roof" with principal rafters and common rafters. A timber roof truss is a structural framework of timbers designed to bridge the space above a room and to provide support for a roof. Trusses usually occur at regular intervals, linked by longitudinal timbers such as purlins. The space between each truss is known ...

Timber design or wood design is a subcategory of structural engineering that focuses on the engineering of wood structures. Timber is classified by tree species (e.g., southern pine, douglas fir, etc.) and its strength is graded using numerous coefficients that correspond to the number of knots, the moisture content, the temperature, the grain ...
Structural notes provide information regarding general material properties (steel or wood grade, concrete strength, etc) or construction requirements (soil compaction, weld procedures, etc). The structural notes also provide information about design criteria (gravity, seismic, and wind loading).
[citation needed] PSL can be made from any wood species, but Douglas fir, southern pine, western hemlock, and yellow poplar are commonly chosen [9] because of their superior strength. The product is manufactured as a 12-by-12-inch (300 mm × 300 mm) or 12-by-18-inch (300 mm × 460 mm) billet in a rectangular cross-section, which is then ...
